The right option is; A) gametes
Gametes are reproductive cells (male (sperm) or female (eggs)) that contain only half the usual number of chromosomes and unite during sexual reproduction to produce a new cell (zygote). The mutation for sickle cell anemia occurs in the woman’s gamete (eggs) and this type of mutation is known as germline mutation; a mutation that occur in the germ (reproductive) cells and can be passed on to an organism’s offspring.
 
        
                    
             
        
        
        
Answer:
Eating healthier foods
Explanation:
There are many things, such as social, behavioral, and biological factors, that can affect the way we feel about life. In the given scenario, we have Harriet, who has made some changes in her life that make her feel better. She made new friends and found guidance from community leaders, which can be defined as a social influence - an influence originating from interaction with other people. She also introduced a new behavior to her routine - writing about her daily achievements. This is healthy behavior, as she is reminding herself about the good things she has done and additionally motivating herself. The only change that can be described as a biological influence is the change in her diet - she started eating healthier foods. This directly affects her body and makes her feel generally better. It's true that there's a healthy mind in a healthy body.
 
        
             
        
        
        
The   deoxygenated   blood  leave  the   right  ventricle  via  pulmonary  artery   to the and   is  taken  to  the   both   right  and  left  lung. That   is  the  deoxygenated blood  is   taken  to  alveolar   capillaries of  the  lung .  As  blood  flows  through  the alveolar  capillaries   it   is  oxygenated   as  carbon  dioxide  leaves.
        
             
        
        
        
Answer:
Carbon fixation
Explanation:
In this reaction, carbon dioxide reacts with hydrogen ions formed during the light stage to form glucose.This is a complex process involving several enzyme-catalyzed reactions. The process requires energy which is provided by the ATP formed during the light reactions.
 
        
                    
             
        
        
        
Answer:
Mass
Explanation:
Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.
The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
